Introduction

  • Turn and shake the bottle gently before use
  • Sprinkle material on leaves or pour into application boxes (DIBOX)
  • In low crops it is possible to distribute SPIDEX mechanically by means of the AIRBUG mite blower

Environmental conditions
Relative humidity should be greater than 75% and the temperature above 20°C/68°F for some hours of the day. Phytoseiulus persimilis does not enter diapause.

Storage and handling
Biological beneficials have a very short life expectancy and therefore need to be introduced into the crop as soon as possible after receipt. Storing them for a period can have a negative impact on their quality and is only possible under the conditions described below. Koppert B.V. is not liable for any loss of quality if the product is stored for longer than recommended and/or under incorrect conditions.

  • Storage after receipt: 1-2 days
  • Storage temperature: 8-10°C/47-50°F
  • In the dark (bottle horizontally)

Appearance

  • Adults: bright red, very active, spherical, stands high on its legs
  • Eggs: oblong, first pink and transparant, later on darker, twice as big as spider mite eggs
  • Larvae/nymphs: pale to light red

Mode of action
Adult predatory mites and nymphs search actively for their prey and suck them dry.

Visual effect
Adult red spider mites that have been eaten change colour from brown to black (in tomato) and can be identified as tiny black dots on the leaves. This should not be confused with living, light-brown to dark-red spider mites.

Important!
The introduction rates of this product should be adjusted to the mode of action of the product and the results that can be expected in the crop where the product is applied. Your local Koppert consultant or recognized distributor will be able to advise you further.
